For observers on Earth, the sun appears as a bright, familiar disk—but what we see is only half the story. Like the moon, one ...

Astronomers have produced the first continuous, two-dimensional maps of the outer edge of the sun's atmosphere, a shifting, frothy boundary that marks where solar winds escape the sun's magnetic grasp ...

Using the combined might of spacecraft scattered across the Solar System, scientists have built the most detailed map yet of the boundary where the Sun's magnetic push no longer accelerates the solar ...

Far above the Sun’s bright surface, a steady stream of charged particles accelerates into space. This outflow, known as the solar wind, starts nearly motionless and then races outward at hundreds of ...

Scientists have developed a new technique to map the magnetic polarity of active regions on the Sun’s far side, a breakthrough that could improve space weather forecasts. The advance comes as NOAA ...

For the first time, scientists have mapped the magnetic fields on the far side of the sun, a region invisible from Earth.

From Earth, we only ever see half of the sun. The other half—the far side—is always hidden from view. But what happens there still matters. Powerful activity forming on the far side can rotate toward ...
